CL-TUMBLR provides a simple interface to Tumblr's API.

Here's some example code:

;; Set the tumblr URI
(setf cl-tumblr:*tumblr-uri* "")

;; Grab the 30 latest regular items
(defvar *reg-items* (cl-tumblr:get-items :start 0 :num 30 :type "regular"))

;; Collect the titles
(mapcar (lambda (x) (cl-tumblr:item-data x "title")) *reg-items*)

;; Get the 10 latest items
(defvar *items* (cl-tumblr:get-items :num 10))

;; Collect the types of the items
(mapcar #'cl-tumblr:item-type *items*)

;; Collect the URIs for items
(mapcar (lambda (x) (cl-tumblr:item-metadata x "url")) *items*)

;; Fetch a specific item
(cl-tumblr:get-item 2044201)
